txt文件上传时需要做一些处理，否则只能显示UTF8格式的txt
////// 文件上传 /// ///public JsonResult UploadFiles() { HttpPostedFileBase postFile = HttpContext.Request.Files["filesave"]; if (postFile != null) { string fileName = Path.GetFileName(postFile.FileName); string fileExt = Path.GetExtension(fileName.ToLower()); string fileSize = postFile.ContentLength.ToString(); long fileNameTem = Common.GenerateLongId(); string sPath = string.Format("/Data/Material/{0}_{1}.txt", fileNameTem.ToString(), fileName.Replace(".txt", ""));//Guid.NewGuid().ToString().Replace("-", "") string viewUrl = string.Empty; string g = Guid.NewGuid().ToString(); if (!Directory.Exists(Server.MapPath("~") + "/Data/Material")) Directory.CreateDirectory(Server.MapPath("~") + "/Data/Material"); string p = Server.MapPath(sPath); postFile.SaveAs(p); if (System.IO.File.Exists(p)) { StreamReader sr = new StreamReader(p, System.Text.Encoding.Default); String input = sr.ReadToEnd(); sr.Close(); StreamWriter sw = new StreamWriter(p, false, System.Text.Encoding.UTF8); sw.WriteLine(input); sw.Close(); } return Json(new { FilePath = sPath, FileName = fileName, viewurl = viewUrl, fileSize = fileSize }); } else { return Json(new { FilePath = "" }); } }
